ELECTRIC FURNACE.

Application le'd August 17, 1923. Serial No. 657,899.

To all 'whom it may concern.:

Be it known that I, JEROME SEcHowsKT, a

lcitizen .of the United States, residing at i Notre Dame, in the county of St. Joseph and State of Indiana,have invented certain new and useful Improvements 1n Electric Fur-- i naces,`oflwhich the following is a specifica- The primary object of my invention is to "provide such an. electric furnace that is extremely simple of construction and' one that may be installed and operated at mini-` mum cost the nature of the same being' such that the furnace may be disassembled for renewal or repair purposes.

Vith the above and other objects in view as the nature of the invention will be better understood, the same comprises the novel form, combination and arrangement of parts set forth in the following specification, shown in the accompanying drawings-and claimed. v

In the -drawings wherein like reference characters indicate corresponding parts throughout the? several views,

Figure 1 is a vertical detail cross section of.

my improved furnace,

Fi re 2 is a transverse section taken substantlally upon the line 2-2 of Figure 1,

Figure 3 is an enlarged cross sectional view through one of the heating coils employed in conjunction with the furnace, and

Figure 4 is an enlarged fra entary elevation partly in cross section t rough a certain portion of the furnace for more clearly disclosing the securing means between difer ent walls of the furnace.

Now having particular reference to the drawings, my novel furnace embodies a casting made up of sheet `metal side walls 5 .front and rear walls 6, a bottom wall 7 an a top wall 8. The side and front and rear walls are preferably integrally joined together the top and bottom Walls thereof bee eating sys-V ing flanged for engagement within'said side l i and front and rear walls and being secured thereto through the medium of a bolt and y nut connection 9, Fig. 4. v

. 'Secured in any desirable 'manner within the casing and ndant from the top wall thereof is a partition 10 that terminates adjacent the bottom Wall 7 of the casing for dividing the same into what maybe termed compartments designated 11 and 12 respectively the -fcompa'rtment `11 being of. relatively lessi dimensions than said' compartment 12.v y

VVithin-said compartment `12 and secured to said partition 10 and the adjacentl side wall 5 of the casing are inwardly extending `Ainverted pan shaped partitions or bafes 13 the length of the same being less than the length of said compartments, each alternate one of the partitions being carried by said partition 1(),.tl1e remainder thereof being carried by the adjacent side wall 5 of said casing.

Extending longitudinally beneath each of said partitions 13 are spaced rods 14 the op-l posite ends thereof engaging through openings in the lang'esof the partition as shown in Fig. 3. Surroimding eachl of these rods 14 is a tube 15-of a suitable insulating material while surrounding each of these tubes isI an uninsulated copper wire coil 16 the coils upon each of said rods being electrically connected to each other while the ycoils carried by each of the partitions are also elec- The top wall ofthe casing above said compartment 7 is rovided with an inlet opening 17 over which is arranged the outlet of a fan casing 18 there being disposed` within this casing a blower 19 that is rotated at high speed through the' medium of a desirable form of electric motor 20 there being necessarily a driving connection ,between the armature shaft of said motor and the shaft of said blower 19. n

The casing 18 is manifestliy provided with an air inlet pipe 21.

Within the com artment 12 wherein there is arranged the efore mentioned electric coils is a water tank 22 that is in communication with a filler spout 23 lthat extends outwardly within the side wall of the furnace casing 'whereby water may be placed Within the tank it' being obvious that the heated air will naturallybecome moistened a slight degree due to thepresenee of this Water.

Above said compartment 12 the tcp Wall 8 of the casing is provided with a suitable number of openings 24 over which are arranged the inlet endsoit air conveying pipes 25 these pipes extending to radiators disposed at esirable Ypoints Within the buildin i he motor 20 is in open circuit with the house current through the medium of a Aswitch located at a convenient point-Within the building as is also the heating element arranged Within the compartment 12 and Whenever it is Ydesired. 'to operate the furnace these switches are obviously closed. A rotation of the motor 20 will cause a rotation of the blower 19 for consequently drawing air through the pi `e 21 and forcing the same downwardly vvit in the compartment 11 inthe direction of the arrows this air passing beneath the partition 10 and then. going 1n acircuitous path between the dif'- 1 erent partitions 13 that carry the heating Acoils this air being obviously heated during lthe course of its travel lfrom the bottom to the top of the casing. 1

'The specific operation together with thev numerous advantages of an electric' `furnaceof this character will be at once obvious to those skilled in the art and even though I have herein set 'forth the most practical .embodiment of the invention With which I am at the present time familiar it is nevertheless to be understood that minor changes may be made Within 'the invention Without departing from the spirit and scope of the appended claims.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is 1. In an electric furnace, a casing divided internally by a vertical partition into sepathe casing to aord communication between rate compartments, said partition terminating 1n spaced relation trom 'the bottom of the compartments', the top of said casing being provided above one oi said compartments with an I opening, air circulating means mounted on said casing and in communication with said openings `for driving air throughsaid compartment and into the remainin compartments, a plurality' of horizonte y disposed batlies arranged in the last named compartments in staggered relation, said baiiles being mounted alternately upon said partition and one of the `"walls of the last named compartment, vsaid baies being of a Width equal to the compartments and of a length less than the length of the said opening and then through said smallv compartment intotthe large compartment, a plurality of inverted pan shaped baffle plates mounted in said last named compartments alternately upon said partition and one of the casing Walls, said balile plates being of a width equal to the Width 'of 'the I. compartment and o'f a length less than the length of the compartment *whereby to provide a tortuous and restricted passage for the air, a plurality of bolts mounted beneath each plate in a transverse row, sleeves of insulation surround said bolts, and electricity conducting Wire coiled around said sleeves.

In testimony whereof I aiiix my signature.

JEROME SECHOWSKI.
